sub procedure CF_WRITE_BYTE(dim byref CtrlPort as byte, dim byref DataPort

as byte, dim BData as byte)

Ports must be initialized, CF must be initialized for write operation (see

CF_WRITE_INIT).

CtrlPort - control port , DataPort - data port , dat - is data byte written to CF.

Write 1 byte to CF. This procedure has effect if writing is previously initialized,

and all 512 bytes are transferred to a buffer.

sub procedure CF_WRITE_WORD(dim byref CtrlPort as byte, dim byref DataPort

as byte, dim WData as word)

Ports must be initialized, CF must be initialized for write operation (see

CF_WRITE_INIT).

CtrlPort - control port , DataPort - data port , dat - is data word written to CF.

Writes 1 word to CF. This procedure has effect if writing is previously initialized,

and all 512 bytes are transferred to a buffer.

sub procedure CF_READ_INIT(dim byref CtrlPort as byte, dim byref DataPort

as byte, dim Adr as longint, dim SectCnt as byte)

Ports must be initialized.

CtrlPort - control port , DataPort - data port , Adr - specifies sector address from

where data will be read, SectCnt - parameter is total number of sectors prepared

for read operations.

This procedure initializes CF card for write operation.
